CEGL007127 Pinus palustris / Quercus laevis / Chrysoma pauciflosculosa / Aristida purpurascens Woodland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Longleaf Pine / Turkey Oak / Woody-goldenrod / Arrowfeather Three-awn Woodland
Colloquial Name: Georgia Xeric Fall-line Sandhills Longleaf Pine Woodland
Hierarchy Level: Association
Type Concept: This extremely dry association occurs on inland, xeric, coarse sand ridges in the Fall-line Sandhills region and Inner Coastal Plain of Georgia and perhaps South Carolina. Species richness is extremely low in this type with on average 18 species in 100 m2. The open canopy consists of Pinus palustris with a mix of shrub oaks in the subcanopy layer, including Quercus margarettae, Quercus laevis, and Quercus hemisphaerica. Chrysoma pauciflosculosa is the dominant dwarf-shrub and is indicative of this type, although Opuntia humifusa and Vaccinium stamineum are also constant. Other characteristic species include Aristida purpurascens, Bulbostylis ciliatifolia var. coarctata, Dichanthelium acuminatum, Selaginella sp., and Galactia sp.
Diagnostic Characteristics: This type is distinguished from other xeric longleaf pine types by the prevalence of Chrysoma pauciflosculosa in the shrub layer and a canopy and subcanopy dominated by Pinus palustris and Quercus margarettae, respectively.
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: Name and description are based on 3 plots from the Carolina Vegetation Survey (vegbank.org\cite\VB.ds.199642.CEGL007127). This type is most similar to ~Chrysoma pauciflosculosa - (Clinopodium coccineum) Dwarf-shrubland (CEGL003946)$$, but is distinct enough from it to warrant designation as a new type. CEGL003946 occurs further south and is a dwarf-shrubland dominated by Chrysoma pauciflosculosa with no trees in the overstory, hence it is in a different USNVC group.

Physiognomy and Structure: No Data Available
Floristics: This xeric association contains an open canopy of scattered Pinus palustris and a subcanopy layer dominated by Quercus laevis, Quercus margarettae, and Quercus hemisphaerica. Other common tree species include Diospyros virginiana, Osmanthus americanus, and Pinus taeda. Chrysoma pauciflosculosa is the dominant dwarf-shrub, but Opuntia humifusa, Vaccinium stamineum, Vaccinium arboreum, and Hypericum gentianoides are also indicative of this type. The herbaceous layer is species-poor and fairly undeveloped. Characteristic herbaceous species of this type are Aristida purpurascens, Bulbostylis ciliatifolia var. coarctata (= Bulbostylis coarctata), Dichanthelium acuminatum, Galactia sp., Selaginella [acanthonota + arenicola], and Stylisma patens. Species richness is very low compared to other xeric and subxeric vegetation types in Georgia.
Dynamics: Fire frequency is less frequent than in subxeric and mesic longleaf pine vegetation types owing to infertile soils and a sparse herbaceous layer.
Environmental Description: This association is found on very xeric coarse, infertile sands of Spodic Quartzipsamments, which are associated with old dune systems along rivers. Silt content and organic matter are low.
Geographic Range: This association is found in the Fall-line Sandhills region and the Inner Coastal Plain of Georgia. Specifically, this type has been documented on Fort Benning, in Chattahoochee County, Georgia, and in Tattnall County in Big Hammock Natural Area. It may also occur in South Carolina, as Chrysoma occurs near the Fall-line in Lexington County. More plots are needed to circumscribe its full distribution.
